At present, most of the DC cooling fans are brushless motors. The brushless motor saves the collector ring and brush for excitation, simplifies the structure, greatly enhances the mechanical reliability of motor operation, and increases the service life. The air gap density can be greatly improved, the motor index is good, and the volume of the motor is directly reduced, which reduces the weight. The brushless motor not only has simple speed control, but also has good speed performance.

The excitation magnetic field of brushless motor does not need the reactive current of power grid, so its power factor is higher than that of induction motor, which can operate at 1 power factor. Compared with induction motor, brushless motor not only has higher efficiency and power factor under rated load, but also has more advantages under light load. The operation efficiency of permanent magnet brushless DC motor is higher than that of induction motor, and the efficiency of small capacity motor is improved more obviously. Brushless motor not only has the advantages of good speed regulation and starting characteristics, good control performance, stable operation and wide application, but also has the advantages of long life, high efficiency, stable performance, high reliability, no commutation spark, low mechanical noise and small mechanical wear And Lihui motor has many advantages that brush motor can't compare with.
